API RP 572: INSPECTION PRACTICES FOR
PRESSURE VESSELS, 5TH EDITION
Pressure vessels are critical components
in various industries, including petro-
chemical, oil and gas, power gener-
ation, and manufacturing. Inspection
practices for pressure vessels are crucial
due to several reasons, including safety
assurance, compliance with regulations,
prevention of failures, and risk manage-
ment. In addition, proper inspection
and maintenance practices can signifi-
cantly extend the service life of pres-
sure vessels. Detecting and addressing
issues early on can prevent the need for
premature replacement, saving costs and
resources.
The American Petroleum Institute
(API) introduced the 5th edition of
Recommended Practice (RP) 572:
Inspection Practices for Pressure Vessels
on 9 November 2023. This latest edition
complements API 510: Pressure Vessel
Inspection Code, which covers in-service
inspection, rating, repair, and alteration.
RP 572 provides enhanced insights into
the inspection practices applicable to a
range of pressure vessels utilized in the
hydrocarbon and chemical industries.
Expanding upon the principles
outlined in API 510, the 5th edition of
RP 572 offers a comprehensive explora-
tion of pressure vessel design, construc-
tion, inspection planning, frequency,
assessment methods, repair procedures,
and record-keeping protocols. It
underscores the significance of safety
precautions and highlights the limita-
tions associated with various inspection
methods.
In addressing safety concerns, the
latest edition places emphasis on two
primary aspects:
Ñ Safety of personnel in prox-
imity to pressure vessels: Regular
inspections are vital for evaluating
the current state of a vessel and
ensuring ongoing safe operation.
This edition is geared toward mini-
mizing the potential for failures,
ultimately enhancing the safety of
employees.
Ñ Safety of pressure vessel inspec-
tors: Acknowledging the inherent
safety risks involved in the inspec-
tion process, the new edition of
RP 572 furnishes detailed guidance
to enhance inspectors’ exper-
tise and knowledge, with the
ultimate goal of improving their
safety throughout the inspection
procedures.
The 5th edition not only refreshes
fundamental content but also integrates
perspectives on emerging technologies
(for example, it revises annexes related to
exchangers and towers). Additionally, it
introduces new material and adjusts the
organization to be in harmony with other
API standards and recommended prac-
tices. The key focus areas include:
Ñ approaches for determining inspec-
tion frequency and conducting
inspections
Ñ assessment of inspection outcomes,
encompassing fitness-for-service
evaluations and subsequent actions
Ñ methods for repairs and the inspec-
tion of repaired components
Ñ procedures for pressure testing
Ultimately, the document provides
direction on analyzing integrity reports
and adjusts its structure for improved
coherence with RP 574: Inspection
Practices for Piping System Components.
The 5th edition of RP 572 serves as a
cornerstone reference for API’s Individual
Certifications Program (ICP) 510 and API’s
Process Safety Site Assessment Program
(PSSAP®) and constitutes an essential
component of the knowledge base
required by individuals pursuing API 510
certification, particularly those aspiring
to become certified Pressure Vessel
Inspectors.

IN DEVELOPMENT
The following section provides a summary of
new standards, drafts, and revisions that may
be of interest to the nondestructive testing and
evaluation (NDT/E) community. This summary is
provided in Materials Evaluation on a quarterly
basis in January, April, July, and October. For the
latest information, please visit the website of the
standards provider.
PROJECT INITIATION
ANSI procedures require notification by ANSI-
accredited standards developers of the initiation
and scope of activities expected to result in
new or revised American National Standards.
The following is a list of proposed actions and
new standards that have been received recently
from accredited standards developers. To view
information about additional standards for
which a project initiation notification has been
submitted, and to search approved American
National Standards, please visit ansi.org, which
is a database of standards information. Note that
this list is not exhaustive.
Ñ BSR/ASME A13.1-202x, Scheme for the
Identification of Piping Systems. This is a
revision of ANSI/ASME A13.1-2023. ASME
A13.1 establishes a common system to assist in

identification of fluids conveyed in piping and
their characteristics.
Ñ BSR/ASNT AI/ML-202x, Uses of AI/ML for
NDT Application. This is a new standard. This
standard establishes perquisites for applying
artificial intelligence/machine learning (AI/ML)
in digital NDT. It provides requirements for data
collection and management and defines criteria
for model selection and development in the
context of NDT applications. After the AI-enabled
system is developed, this standard stipulates
requirements to evaluate its performance, vali-
dation, deployment, and integration followed
by maintenance, feedback mechanisms,
training, risk assessment, and mitigation strat-
egies including the need for mandatory proce-
dures for these processes. This standard will
serve as a blueprint for formulating subsequent
standards specific to various modalities.
Ñ BSR/ALI ALCTV-202-202x, Standard for
Automotive Lifts – Safety Requirements for
Construction, Testing, and Validation. This is a
revision of ANSI/ALI ALCTV-2017. This standard
covers safety requirements for the design,
construction, testing, and validation of automo-
tive lifts used for vehicle service and parking.
These covered automotive lifts may be of the
following types: manually driven, power driven,
stationary, mobile, and lifts tilting the raised
vehicle in the pitch direction.
Ñ BSR/AWS D14.0/D14.0M-202x, Machinery
and Equipment Welding Specification. This is a
revision of ANSI/AWS D14.0/D14.0M-2023. This
specification establishes design, manufacture,
quality, inspection, and repair requirements
for carbon, low-alloy, and alloy steel welded
connections in machinery and equipment. It
addresses topics including weld joint design,
workmanship, quality acceptance criteria,
nondestructive examination methods (visual,
radiographic, ultrasonic, magnetic particle, and
liquid penetrant), repair of weld defects, and
post-weld heat treatment.
Ñ BSR/AWS D14.9/D14.9M-202x, Specification
for the Welding of Hydraulic Cylinders. This is
a revision of ANSI/AWS D14.9/D14.9M-2022.
This specification provides standards for the
design and manufacture of pressure-containing
welded joints and structural welded joints
used in the manufacture of hydraulic cylinders.
Manufacturer’s responsibilities are presented
as they relate to the welding practices that have
been proven successful within the industry in
the production of hydraulic cylinders. Included
are clauses defining procedure qualification,
performance qualification, workmanship, and
quality requirements as well as inspection
requirements and repair requirements.
Ñ BSR/AWS D8.11M-202x, Specification for
Automotive Weld Quality – Laser Beam Welding
of Aluminum. This is a new standard. This
document will standardize laser-beam-weld
inspection procedures and establish guidelines
for process control and quality acceptance of
aluminum laser beam welds in automotive
body applications. Aluminum use in automo-
tive body structures, now including battery
trays for electric vehicles, continues to expand.
Development of this specification is the natural
next step for the AWS D8E Subcommittee
following the recent release of AWS D8.10M:
2021, Specification for Automotive Weld Quality
– Laser Beam Welding of Steel.

WEBINAR
Join the upcoming ASNT Virtual
Section meeting on 18 January
2024 at 2:00 p.m. (ET) to learn
about the early development and
in-service assessment of locomo-
tive undercarriage thermal inspec-
tion systems, which are also known
as in-track thermal detectors. The
informative presentation will be
delivered by Anish Poudel, PhD,
who will discuss how MxV Rail
installed thermocouples and data
loggers on three different styles
of locomotives. This allowed them
to record the real-time tempera-
tures of the high-load mechanical
components while the locomotives
were running on the network.
By attending the webinar, you
will discover how the continuous
data obtained from the onboard
unit was useful for determining
warmup profiles and average
operating range temperatures for
the various components. Register
today at asnt.org/virtualsection.
